Hi skycaptain - are you a pilot? My car is a 2006 with 80 something miles on it (couldn't read the exact numbers when I turned it in for service because it was dead). I had a GS 300 for 9 years and loved it. When I heard they were coming out with a SUV Hybrid I got on a waiting list and had to wait 10 months to get one, so I'm pretty sure it's one of the first ones off the line. I've had it new since October of 2005. This is the first time in 15 years I've ever been stranded by a Lexus.

Hi, I am glad that I found this forum. However my car is 2008 model about 38k miles and had the same problem as I read. The car stalled in the middle of intersection. Just went dead. The accelerator didn't work, the handle was locked. But the radio was on, the windows go up/down, AC was on. I couldn't even turn on the hazard light. I managed to push the car with the help to the side and 15 minutes later I was able to drive back again. About 10 months ago, the car didn't turn on and the next day we managed to turn on so we brought to the dealer and they replaced the battery. The car is in the dealer now and we are waiting for the answer. We are not sure what the problem is but after I read 2006 models stalled on highways... that could happened to me too... so scary.

I too was concerned about this poorly designed inverter problem. I opted to purchase an RX330 with 103k miles instead of a hybrid. Runs beautifully. She still can use unleaded vs. premium fuel and gets around 25mpg if we baby her.
The only downside to purchasing a used Lexus is if the previous owner has not done their regularly scheduled maintenance. Repair costs are, well, shall I say significant at Lexus Service centers?

The inverter has been recalled, and Lexus will replace for free. At least on the 2006 model.

After learning that the inverter is a ten thousand dollar part, I would no longer buy the hybrid model either. Apparently, going green has it's downsides. Wind power also uses inverters (solar too), if the wind speeds are too high for a sustained period of time, you can burn out a 4-6 thousand dollar inverter. So, for wind, you have to really match wind speed to the inverter (for efficiency). This means "dumping wind", during highly sustained gusts or storms.
I wonder if high sustained freeway speeds can cause these inverters to burn out. If they built these to have a maximum efficiency at 60 mph can 80 mph over time burn out the inverters?

Last Thursday I had the very unpleasant experience of having my 2006 Lexus rx400h completely die while I was on the freeway. It was towed to Lexus and I was told my inverter water pump is dead. They are quoting me $1200 to fix it. They won't be able to tell what else might be wrong, such has the inverter itself completely failing, until the pump is installed.
I called cooperate lexus and as of right now, I'm not overly thrilled with their response. I flat out asked that if once the new pump is installed and we find that the inverter is still working, will they not replace it in spite of the many documented failure cases? No was the reply. So essentially the inverter will need to completely fail, possibly while I'm driving and not able to pull over with possibly hurting someone or myself. Nice lexus . . .
#106 of 110 Brake Calipers replaced
Dec 04, 2012 (12:09 pm)
For a while I have had a rattle/rumble from the rear of my car especially when going over bumps. No one could diagnose the problem and eventually I took it to a Lexus dealership (there isn't one in Charlottesville!) who told me that I needed to replace the rear brake calipers which were loose. Apparently they couldn't tighten them as a rubber bushing had failed. So $1,200 later I have new brake calipers and rattle has gone. The service dept. said they had never seen this problem before. Of course it's out of warrantee by about 12 months! Why should I need to replace the calipers just because a bushing has failed? Anyone else have this problem?

I did not have chance to update about our car but the dealer kept it for about 3 weeks, said drive fine everyday, could not find a problem and could not simulate the problem. They said the battery was actually fine but they changed it anyway (changed it twice within a year). Meanwhile we talk to the corporate to sell the car. Although the car is certified pre-owned, they couldn't help much. We told the dealer that they can't simulate the problem is already the big problem. They gave us a low price, we lost a lot of money but we just felt bad to sell this kind of car directly to someone by ourselves. The dealer even said 'Now we can't tell this problem to the sales person!' and put 30% mark up on and is selling it. I can't trust this model. We owned Prius twice, never had any problems. One has 120k miles on, still fine. Prius has been made a lot and been around long time, probably more reliable. Guess what? We purchased Prius again. I will report this Lexus to the government. We should not bare this kind of problems for such expensive cars!!
